GAS-BURNER,

SPECIFICATION forming part of Letters Patent No. 399,104, dated March 5, 1889.

Application filed March l5, 1888. Serial Noi 267,249. (No inodeh) To all l/mnt 'il 12mg/ concer/z:

Re it known that LFEENANDO Wurm, a resident oi' Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Iniprovement in Gasj v of the burner it may be placed in either posilurners; and I do hereby declare the following to be a full, clear. and exact description i thereof.

My invention relates to gas-burners, and

more especially to a burner for illuminating purposes.

In burning gas tial in obtaining the greatest luminosity that the. gas should be as highly heated as possible before it reaches the point oi' combustion. To obtain this result is the object of my invention, as well as to provide a burner which can be economically constructed.

To these ends my invention consists in certain combinations of parts, more fully hereinafter set forth.

To enable others skilled in the art to make and use my invention, l will describe the same more fully, referring to the accompanying drawings, in which- Figure l. is a central vertical section of my improved burner, and Fig. 2 is a side view of the burner.

In eonstructin my improved burner, a body,

for illumination it is esseu- 1 o, which is preferably bell-shaped, has extendi from the body a, so that a perfect combustion ing up through a threaded opening, c, at its smaller end, a pipe, d, which has one or more outlet-openings, e, for the 'escape of the gas. The pipe d serves as the supply-pipe of the burner, and, though it may be plugged at its upper end, I prefer to form threads d' thereon and extend the same above the edge of the body a, so that it can engage athreaded opening, j', in a cover-plate, g, which plate has the outer edges of its under face ground ofi", so that the plate will fittightly against the top edge, a', of the body a when the plate is screwed down on the threaded end d of the pipe d. By this construction the supply-pipe (Z also serves to hold the cover-plate g securely against its seat a on the body o without the plug 7a..; but when it is desired io hang the burner from theservicc-pipe the lower end olf the pipe d is closed by a cap and the servicepipe screwed into the threaded opening f, instead ot the plug 71.. Thusby the construction tion. lo regulate the flow of the gas from the supply-pipe (I into the chamber i, formed by the body d and the cover-plate g, a sleeve, j, incloses the pipe d at its outlets e and extends up to the cover-plate g, so that an outlet for the gas into the chamber i is formed between the cover-plate and the top of the sleeve j, which outlet may be varied more or less in size by moving` the sleeve to and from the cover-plate. The preferable method of attaching this sleeve tothe pipe d so that it can be moved up and down is to form a threaded ange, j', on the lower end of the sleeve, which flange engages threads formed on the pipe d., which permits the necessary7 amount of movement for the adjustment of the position of the sleeve by screwing the sleeve up or down.

To permit the escape of the from the chamber i", so that it can be burned, a series of downwardly-projecting holes, t, are formed i in the body a a short distance below its edge a', the effect of the downward inclination of the holes being to throw the flame outward is obtained, as the flame does not lick the sides of the body and prevent the access of air to the inner side of the llame. In order to prevent the llame from curling over the top of the cover-plate g and insure that it will have a vertical direction, an upwardly-extending flange, m, is preferably formed on the top of the cover-plate g at its outer periphery, the flange having a slight outward inclination.

The operation of the burner is as follows: The gas coming in the pipe d either from the top or bottom passes through the outlets e,

and is deflected upward by the walls of they sleeve j until it strikes against the cover-plate g, and then shoots laterally out between the cover-plate and the top of the sleeve j, licking the under surface of the cover-plate as it moves toward its outer periphery, finally passing down the wall of the body a. u ntil it escapes IOO from the holes I, and then, mixing with the air, burns. After the gas has burned ashort time the cover-plate g becomes heated by the hot gases and air which are above it, and thus the unburned gas as it shoots along the under surface of this cover-plate is quite highly heated by the time it reaches the outer peripheryof the plate, and is still further heatedl by its contact with the walls of the body ctbefore it reaches the holes Z, issuing from the' latter at the proper temperature to secure perlect combustion for illuminating purposes. As the pressure of the gas forces the latterout of the holes l, the inclination of the holes throws the flame away from the body a, so that air .can have access to the inner side ol the flame and prevent smoking. '11 en the pressure on the service-pipe is high, the sleeve] is screwed up until a smaller space is lett between the top of the sleeve and the cover-plate g, and thus a smaller amount of gas will pass into the chamber 7. If the pressure is low, the

sleeve j is screwed down, so as to make the outlet into the chamber the maximum.

My improved burner gives a White light of great illuminating' power with a minimum exl penditure ot' gas.

Having now described my invention, what I claim is- 1. In a gas-burner, the combination of the body. d, the gas-supply pipe d, extending` into the same, said pipe having outlets e therein and having its upper end threaded, the coverplate g, screwing onto the end of said pipe and resting against the top of the body a, and

. a cap or plug, 7L, closing the end of the pipe d,

substantially as and for the purposes set forth. 2. In a gas-burner, the combination of the body a, having the outlets l, the pipe d, eX- tending up through the body and having outlets e therein, the cover-plate g, screwing onto said pipe and resting on said body, and the regulating-sleeve j, screwing onto said pipe and having an enlarged portion inclosing said outlet e and extending up toward said cover-plate, substantially as and for the purpose set forth. In testimony whereof l, the said FENAND \\'THITE, have hereunto set my hand.

FERNANDO WHITE.
